Returns the safe area of the screen in pixels (Read Only).
On some displays, certain areas of the screen may not be visible to the user.
This may be caused by the display's shape being non-rectangular or in the case of TV displays, it can be caused by overscan.
Avoid placing user interface elements in areas outside the safe area rectangle.
The maximum size of the safe area is the screen resolution in pixels and is defined as Rect(0, 0, Screen.width, Screen.height).
